Help ...
Recently received a Dendrobium Nobile as a gift ... the orchid did have mealy bugs for which I treated with alcohol.
It also had some suspicions black areas on the undersides of the leaves that I treated with hydrogen peroxide .
I also trimmed the dead roots and repotted.
Sadly I'm still struggling with yellowing leaves , suspicious black spots ... and the spots seem to be putting the leaves ...
I'll attach pics ...
Any help would be appreciated
